This species is known from the type locality, from the vicinity of Cacazú, 900–1,200 m asl, Pasco Region, Peru (Duellman and Hedges 2007). It is now also known to from Finca Panguana, 250 m asl, Huánuco Region, extending its known geographic range ca 115 km NNE from its type locality (Rödder and Schlüter 2009).
Habitat and Ecology
The species is known only from humid lowland and lower montane forests on the lower Amazonian slopes of the Cordillera Yanachaga in central Peru. All individuals were on leaves 30-60 cm above the ground at night (Duellman and Hedges 2007) or under small stones in a dry stream bed (Rödder and Schlüter 2009). It is presumed to breed by direct development.
The species is only known from the type series, comprised of five specimens, and an additional six specimens collected in 1998, so the population size and trend are unknown. The species was not recorded during recent (2014) surveys in the Oxapampa area (A. Angulo pers. comm. December 2017).
The threats to this species are unknown.
It has been recorded from Área de Conservación Privada Panguana.
More information is needed on this species' distribution, population status, ecology and threats.
